Answer:
Given the statement: if y =3x+6.
Find the minimum value of
Let f(x) =
Substitute the value of y ;
Distribute the terms;
The derivative value of f(x) with respect to x.
Using
we have;
Set
then;
By zero product property;
and 2x + 3 = 0
⇒ x=0 and x =
then;
at x = 0
f(0) = 0
and
x = -1.5
Hence the minimum value of is, -5.0625
